The ruling on the increase in traffic fines if their payment is delayed?

Question:
The second question regarding traffic violations: they say that it is riba (usury or interest), so I do not know about the increase in it, because there is a doubling from three hundred to five hundred. Is this increase riba or not? Now, the third question.

Answer:
As for traffic violations, one is limited to the prescribed fine, and it is not increased if it is delayed. It is not permissible to increase it, because this is riba. This is like the increase in a debt when it is delayed; it is not permissible. Yes.
